Asami made her adult video debut on October 29th, 2005, and has been working for studios Alice Japan and S1 ever since. She stars in a new video for each studio every 1 to 2 months. In addition to this, she has worked as an actress in several softcore films and TV series, and was featured as a cabaret club hostess in PlayStation 2 videogame Yakuza 2.

She released a solo single before becoming a leading member of the female idol group Ebisu Muscats, whose 25-odd members are mostly issued from porn or nude modeling.

Asami was born in Gunma prefecture on March 24, 1987 and made her AV debut in October 2005 at the age of 18.[1] She has been under contract from 2005 with two large Japanese AV studios, Alice Japan[2] and S1 No. 1 Style.[3] She has made about one movie a month for each of them since the beginning of her career. Most of her videos with S1 have been with director Hideto Aki while her Alice Japan videos have been primarily directed by Yuji Sakamoto. Both studios specialize in the "softer" type of pornography with straight sex scenes involving a solo actress, little or no storyline, and an avoidance of the more extreme activities of Japanese porn.[4]

Asami has been involved with a number of unusual projects for Alice Japan, mostly with director KENGO. Among these are Amateur Actor Audition – Yuma Asami,[5] released in 2007, where she interviews 10 potential AV actors between the ages of 19 and 41 and tests their abilities by having sex with them. On the opposite side of the coin, in the 2008 video AV Actress Audition – Yuma Asami,[6] she acts as the company rep interviewing 10 aspiring actresses. She has them disrobe, masturbate, and even take part in fellatio and sex scenes with actors with some coaching in technique from Asami. In another video from 2008 (Number One Idol Yuma Asami Produce Real Virgins)[7] she meets specially selected "virgin" fans who are gently initiated into sex by Asami. In the 2008 video Hypnotic Pleasure,[8] the plot has her being hypnotized and made to do various embarrassing things including engaging in sex acts while believing she has never had on-camera sex before, and in a further 2008 video (Yuma Asami and 100 Onanists),[9] she inspires and occasionally lends a helping hand to "100 eager and willing fans" while they masturbate.

In June 2010, Asami starred in one of the first two AVs made in 3D, the S1 produced Attracting The Best Stereoscopic 3D Yuma Asami Sex BODY. The release of the two videos matched the introduction of 3D televisions by Sony and Panasonic and were expected to increase sales of the TVs.[10]

Outside of her hardcore video activities, Asami has also made several "gravure" videos, which are essentially glamour films which may include nudity but no sexual acts. (See the Filmography for details)

In another genre, she was also in an erotic horror pink film, Template:Nihongo, directed by Hideo Jojo and co-starring Japanese AV actress Yuria Hidaka. In the movie, which premiered in Osaka April 2008, Asami is the mysterious and deadly proprietess of an inn.[13][14] The film was released as a DVD in October 2008.[15]

In 2006, Asami was featured as a Cabaret Club hostess in the PlayStation 2 videogame Yakuza 2.[23]

Asami showed off her singing voice by releasing her first J-pop CD, Resolution, in January 2008. The CD comes packaged with a bonus DVD which includes images, a making-of video and a music video.[24][25]

She has also been active in advertising making promotional videos for the adult website Tospo.jp with the QR Code for their site covering her breasts.[26] She also appears on a T-shirt marketed in a collaboration between Cex Work, a new company started up by photographer Yasumasa Yonehara, and the apparel label THE MASK. The T-shirt, released in October 2007, featured a semi-nude photo of Asami taken by Yonehara.[27]

Asami has been one of the most popular actresses in Japan since her debut and regularly places at the very top in DVD sales and rentals.[28][29] The DMM website listing of the top 100 AV actresses by sales ranked her as number 1 in both 2006 and 2007.[30][31]

Asami was recognized by AV fans for her work by winning the Grand Prix award at the 2006 AV Actress Grand Prix.[32] In 2007 her S1 video Hyper Risky Mosaic – Special Bath House Tsubaki made with 11 other S1 actresses won the First Place Award at the 2007 AV Open competition.[33][34] In addition, at the annual 2008 Adult Broadcasting Awards (combined with EROIDE女祭り2008 or "Erotic Ladies Festival"), a competition for the hottest actresses from adult TV channels on satellite broadcaster SKY PerfecTV!, Asami won the award for "Most Appearances" in 2007. She wowed the crowd by bending over several times to expose the tops of her breasts.[35][36] Her November 2008 video Double Risky Mosaic, Rio & Yuma was the S1 entry in the 2009 AV GrandPrix where it won the top GrandPrix Award as well as taking the prizes for DVD Sales and Package Design, the Retailers Award, and the Best Featured Actress Video Award.[37].
